Editing Gulf Coast of the United States (section)

===Rising sea levels===
Due to the release of greenhouse gas emissions, glaciers and ice sheets are melting and expanding the oceans. The United States coastlines are projected to rise 1 foot in three decades or between 10 and 12 inches on average by 2050.<ref name="ToriCBS">{{cite news|date=2022-02-19|url=

Powell |first=Tori|work=CBS News|accessdate=2023-08-30}}</ref> The Gulf Coast will likely see the biggest change, with sea levels expected to rise between 14 and 18 inches. The Global and Regional Sea Level Rise Report predicted more frequent, major and destructive high tide flooding events along with taller storm surges by 2050 after scientists determined high tide flooding has been "increasingly common" over the past few years due to the rising sea levels.<ref name=ToriCBS /> The impacts are expected to be dramatic. Low-lying coastal areas are expected to experience multiple factors, including increased levels of flooding, accelerated erosion, loss of wetlands and low-lying terrestrial ecosystems, and seawater intrusion into freshwater sources. Rising sea level and erosion will also imperil critical habitats for many commercially important fisheries that depend on inshore waters for either permanent residence or nursery area.<ref>{{cite web|url=https://coastalscience.noaa.gov/project/predicting-impacts-sea-level-rise-gulf-mexico/|title=Predicting Impacts of Sea Level Rise in the Northern Gulf of Mexico|work=coastalscience.noaa.gov|accessdate=2023-08-30}}</ref> In 2021 alone rising sea levels cost the United States approximately $2.6 billion in relief efforts and caused at least seven deaths.<ref name=ToriCBS /> By 2051, the cost of flood damage is expected to increase by 61%, or $32 billion.<ref>{{cite news|url=
